Answer-Yes   Evolution is very random as it is based on mutations in the genetic code of organisms, although this process is random natural selection is NOT random and it is one of the main principals of this theory. Answer 3 Yes, and no.
Natural selection will only cause evolution if there is enough genetic variation in a population. Before the discovery of Mendelian genetics, one common hypothesis was blending inheritance. But with blending inheritance, genetic variance would be rapidly lost, making evolution by natural selection implausible.
